The new NA5 pump innovation from Nilfisk-ALTO has focused on providing superior cleaning power and even higher durability. The wobble disc pump unit is not only robust and cost effective – it is also quiet, making cleaning more comfortable. No compromise has been made on quality materials and lifetime.
- Ceramic piston sleeves offer high resistance to wear and tear
- Brass pump head offers longer lifetime
- 1450 rpm slow running motor continues to power the new pump, offering a major reduction in sound level and unbeatable durability.
Flow Activation
The flow activated un-loader technology is based on the traditional KEW systems – proven for more than 35 years. The start and stop impulses for the motor are created by the movement of water – and not by a drop or increase in pressure in the pump.
In 2009, Nilfisk-ALTO launches the unique flow activated control system on the lines NEPTUNE 4, 5 and 7 FA. This unique system offers several advantages, especially user comfort and safety as well when the machine runs in by-pass:
- Increased user comfort when machine is in standby mode: No residual pressure in the hose and gun when the unit is in by-pass. The hose is easier to move around. The absence of pressure in the hose also offers a higher level of security.
- Increased lifetime: Small water leaks in accessories or piping systems will cause the motor on pressure activated systems.
- to start and stop – over time reducing lifetime, or even causing the breakdown of the machine. With the flow activated un-loader, small leaks will reduce motor start-stops – and thus prolongs the lifetime of the machine.
- When activating the spray gun, the gradual increase in pressure reduces start recoil force and is more comfortable to use.
- Easily serviced system with good access to key components.
- Low pressure on the pump head.
The flow system does have some constraints:
- Lower flexibility to different nozzle sizes than pressure activated systems
- VarioPress solution not feasible – flow/pressure regulation should be done at the pump head.
The products retain the water break tank in order to also maintain the high pressure chemical function. However, this break tank alone is no longer enough to ensure the product fulfills the EU water by-laws. The user should equip his water network with the new BA valve also.
In our hot water range, in association with the water break tank and the new backflow preventer system, the NEPTUNE 4, 5 & 7 FA line is in full compliance with EN 1717 and EN 60335-2-79.
